The Importance of Hand-Washing

Thankfully, there are measures everyone can fancy keep the virus cornered. And a teacher from Idaho is spreading awareness with a jaw-dropping post that has gone viral. Jarales Annice Metcalf shared photos of a science project she did together with her class, writing alongside a series of photos, “We took fresh bread and touched it. We did one slice untouched. One with unwashed hands. One with hand sanitizer. One with washed hands with warm water and soap. Then, we decided to rub a bit on all our classroom Chromebooks.” The result: “So DISGUSTING!!!”

Metcalf pointed out that yes, the school typically sanitizes the Chromebooks but didn’t for this experiment, the results took three to four weeks due to the bread’s preservatives which extend shelf life, and the bread was placed in tightly-sealed freezer Ziploc bags.

“If the bread had been exposed to air and moisture, the experiment may have gone faster,” Metcalf tells Parents.com. “The breads that were very clearly exposed to different germs grew mold quicker. And ones touch by clean hands plus the soap and water ones were not exposed to the germs that cause the mold growth to quicken.”
